Section 1-1
The four major areas of science are?
Earth science, Life science, Chemistry, and Physics
A series of planned steps used by scientists to solve problems
Scientific Method
a measuring system used by scientists around the world
International System of Units (SI)
the variable in an experiment that is not controlled by the scientist
dependent variable
the unit of measurement used to measure a tiny ant's leg
millimeter
the study of weather
Meteorology
The first step in solving a problem
State the problem
Standard unit for length
meter
when you make your data table you are using which variables
both independent and dependent variables
Tool used to measure the mass
balance or digital scale
The study of objects in space
astronomy
You make this when you are analyzing the data from your experiment
a graph
Standard unit for volume of a solid
cubic meter or cubic centimeter
the variable controlled by the scientist
independent variable
If 100 milliliters of sea water have a mass of 125 grams, what is the density of seawater?
1.25 grams / milliliter
the study of the physical and chemical properties of Earth's oceans
Oceanography
when you design the experiment you create one of these
a data table
the measure of the amount of matter in an object
mass
The first step in your experiment
gather the material needed
the measure of gravitational force on a mass
weight
The study of Earth, its matter, and the processes that form and change Earth.
Geology
In your conclusion you state this
if my hypothesis was correct
the formula for density
density = mass / volume
To "analyze" the results of the experiment, means this.
Make some sense out of the numbers by creating a graph
The density of water
1 gram per ml or 1 gram per cubic cm
